I have a Toshiba Satellite laptop (circa 2003). I know my laptop battery has been drained for a while and I was almost solely relying on the AC adapter's juice to power my machine. Recently, I lost all power to the laptop. I thought perhaps my battery had finally had it so I bought a new battery. Well, then I couldn't charge my battery, so I bought a new AC adapter. I still have no juice. It looks like the AC adapter is working (the light is on it to show it's getting power) but it's not transferring that power to the machine.

I think it may be a bad connection between the adapter plug and the laptop. I don't know how involved of a fix this is.

Any suggestions on what type of fix might be needed? Is it better to just scrap this laptop and get a new one? Thanks for your help!

Since i bought a new laptop E7270, is it allowed to use my power adaptor my old Dell E6420 also for the new one?   If so i can use one adaptor at home and another in office and dont need to carry the power adaptor always.
Will this impact the battery performance of the new laptop?

A:If it is possible to use the power adapter of E6420 for my new laptop E7270? Will it impact the battery of the new laptop?

If the connector fits (it may not - the older systems use a much larger barrel connector than many of the new ones), AND the power (wattage) is equal or greater, yes.

First of all Im pretty tech savy so you can talk to me in technical terms. Ive repaired countless computers for many people and I never came across anything like this. This is the problem...
 
Sometimes when I move my laptop or even type there is a complete loss of power. Everything completely shuts off. It happens whether my laptop is plugged in the AC adapter or not. I bought a new battery just in case it was that and its still happening even with the new battery. Event Viewer System logs tell me nothing except that is recovered from an unexpected shutdown. I suspected that maybe there was something loose inside so I took the laptop completely apart and put it back together... still im getting the same loss of power.
 
Now here's a hint that can possible be causing this. When I get this loss of power I cant turn back on my computer unless I unplug the AC adapter and remove the battery for a few seconds and put it back in.
 
Any idea's guys? Ive searched the web and havent found much on this issue nor a resolution so if we do find a solution bleepingcomputer.com might be one of the first to figure it out. If need be give me a better suggestion for the title of this thread so it can be searched for easier. Thanks in advance guys, lets see if we can figure this out.

I bought a refurbhsed Pavillion 17-G126DS.  I charged the notebook upon delivery.  The charging light on the computer by the AC adapter input was red when I first plugged it in, then turned white - assuming the battery is fully charged.  I unplugged the AC adapter and turned the computer on.  It worked fine for about an hour.  Then, the computer turned off.  Nothing.  No light on the power on button, nothing.  I plugged the AC adapter on, thinking the battery was old, tried to run the laptop off of AC power, and nothing happened.  I have run the diagnostic on the battery (PASSED) and the adapter (PASSED).  Just today, I tried it again.  The battery has been charging, the white light is on, turned on the computer, and, when plugging in the adapter, the computer turned off and the battery light shows red.  The computer will not turn on. Should I get a new  AC adapter? Thanks! Susan

Just replaced the battery in my XPS 1340 and found out I have charging issues. When I plug in a charger, Windows sees it but won't charge the old total depleted battery, instead, runs off ac power. Tried a different charger and a new battery with 30% charge but same results. As a last chance effort, I replaced the male prong power adapter in the computer. Now Windows doesn't see the charger and will not run on ac. 
Is there something in the Bios that needs to be done to fix this or am I to assume it's a motherboard issue and retire this little workhorse.

Dead batteries cannot be charged. Remove the dead battery and try using just the original dell adapter that came with the laptop alone. You cannot use other models adapters or batteries.

I am having Inspiron-6400 (XP SP3) laptop. 2 years old. Suddenly I am getting the following message for the past two days:
"Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation."
That error message comes when I plug in the AC adapter to go to AC from battery.
It results in Battery not charging. That is a big problem. The tray-icon just shows 'On AC Power' and the 'Charging' indication does not appear any more.
A related message is also seen when I reboot the laptop, at the start itself. That message adds a suggestion by saying 'Try to reseat the power adapter'. Reseating it does not help. Though, a couple of times it helped. So I am not sure what this mechanical / reseating thing has to do with this error.
Overall, it is frustrating. It will be great if someone can help me with the exact solution for this, other than going to Dell requesting for paid-service support.

Hi, my girlfriend in Beijing has an Acer Aspire S3 latop. She bought a new battery for it a while back and told me it was no good. I was in Beijing recently messing around with it and found that actually the battery is fine (lasts for >4 hours) but when unplugged and running on battery power, the laptop often just cuts out suddenly (loss of power). I took the battery out and had a look and cleaned all the connections but they seem fine.

The next part is the strange part and which I hope might give someone a clue as to what's going on...

When it cuts out, it will never restart again unless the mains power cable is plugged back into the laptop. As soon as that's done and the power button is pressed, it starts up again and the cable can be taken out immediately (I mean immediately - you can plug the cable in, push the "power on" button and pull the cable back out in less than a second) and it will start up and run fine on battery again... until the next time it suddenly cuts out without warning.

Because any unsaved data is lost and because the laptop cannot restart without the power adaptor, this very portable and light laptop is now reduced to having to be kept at home all the time and plugged in, which is exactly the opposite of what she bought it for.

Anybody have any idea what the problem could be or suggest some tests that could be done to find out? She took it to a local computer shop but the guys there had no idea.

Thanks in advance for any adv... Read more

I have a Dell E1405 Inspiron laptop with a 100% battery charge. The issue is that the computer will not function without the adapter plugged in, rendering the battery as dead-weight. In the boot menu, the battery is showing as "Idle: 100% charged". However, Battery health is telling me "This battery can no longer provide sufficient power to your system and needs to be replaced'. So, I'm wondering, is my battery bad or is my PC not synchronized with the battery?

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. and there is no cross reference.

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Again, no mention of the numbers Kensington uses on their site.

I have scoured the internet for a similar problem/solution but to no avail. It seems I am the first person in the universe with this problem.

Backstory:

A few months ago, on my ASUS g60 vx laptop, I would notice that while gaming and doing anything really, with the laptop plugged in, it would randomly shift, rapidly, between 'Battery Mode' and 'AC mode' as if I was rapidly plugging and unplugging the AC adapter. It seemed almost as if I shifted it around and made sure not to move it, I could get it to remain in 'Plugged in, charging' mode. So I did that for awhile.

Things got worse and I eventually got a message saying my battery was most likely dead. I got HWMonitor and sure enough, it said the battery was pretty much fried. So I took the battery out completely and just used my laptop plugged in for months with no real problems.

Then Christmas came along and I asked for a battery from my in-laws. They got the exact battery for my laptop, I'm 100% sure of it. I slid the battery into place, it fit perfectly. I turned on my computer and saw the batter had like 33% charge, which I'm assuming it shipped with. Problem is, it wasn't charging the battery. I was still just using the AC adapter power apparently.

For days and days it stayed at exactly 33%. Never would charge. Even if I shut down my computer and left the charging cable in, nothing. So I start my computer, and take OUT the ac adapter. What do you know, it starts draining ... Read more

Hi all

I have an HP 530 laptop (1.6 dual core, 1gb memory, 250gb HDD (was 80gb), windows 7 ultimate 32-bit build 7600 (was vista home basic))

My PC runs like a dream. Recently it started giving me problems though. It dies when it wants to. There's no pattern to it.

Sometimes I'll run it on full battery and it'll hold on for 2 hours. Other times full battery keeps on going for 5 mins and then dies indefinitely. Okay sure, you'll say I should replace the battery, but that's not all.

If I run the PC on AC adapter it can sometimes keep on going without the battery for a while. Other times it'll die after 2 mins. Sometimes it charges the battery full and then keeps on going with the battery the whole day long, other times it discharges a full battery in 20mins and dies. If I unplug the AC adapter for a while and plug it back in it seems to solve all the problems for a short while.

If I delete the AHCPI battery manager in Device manager settings it also solves the problem for a short while. These problems only started when I installed Windows 7.

I have deducted that it could be that:
1. I need to replace the battery.
2. I need to replace the AC adapter.
3. I need to go back to Vista or XP
4. I need a BIOS flash.
5. I need a software fix or setting on Windows 7 of some kind.

Somebody please help!!!

Hi FriedBiltong,

It could be the AC cord or jack. You can easily check it out by moving the cord, usually close to jack. Look at the light, there you can see if power is connected.
Laptops works without battery too, so you can skip that part too.

A:No Ac Power or Battery power to Laptop

Sounds like a major failure in the laptop.

You can buy adapters for laptop HDD to Desktop IDE drives, quite cheaply. That will allow you to access the files on the hard drive.

USB cases are also quite reasonable for laptop hard drives and give an easy way to access the drive.

One year later, I'm back with another problem! I just hope this is the correct forum...

I purchased the laptop I'm using about two years ago. For those two years, I have never removed the battery, but have used AC power nearly always, with the exception of a few quick trips and a couple of hours once every week or two. Initially, the battery lasted about 2 hours on a good day, with Wi-Fi enabled. A few weeks ago, that was reduced, seemingly instantly, to about 5-10 minutes. Upon doing some research (which I should've done when I first got the laptop), I'm pretty certain that the battery is about to kick the bucket.

What worries me, though, is how the laptop seems to be becoming increasingly hotter these past few weeks. Despite the fact that my battery hasn't been involved in any recalls, the paranoid side of me is hesitant about leaving it in for much longer. For now, however, being able to afford a new battery is up in the air (that's a nice way of saying not an option). So, I attempted to remove the battery and use only AC power. About three seconds after I turned the laptop on, it shut off. Upon a second and third try, it wouldn't turn on at all. I let it rest for about 30 minutes and tried again; it lasted long enough to show the Windows XP logo (ten or so seconds) and again shut off. I popped the battery back in, and it turned on without a problem.

So I'm left wondering: what's wrong? Has my laptop become dependent on batte... Read more

A:Laptop won't run on AC power without battery.

I've seen a number of laptops that won't run without the battery, so I'd say that could be normal. A laptop shouldn't damage the battery pack with it plugged in continuously. My wife's laptop has been plugged in most of the time for a year, the battery is just fine. The charging circuit in the laptop should not overcharge the battery.

If the laptop is getting hot, you might consider blowing the dust out of the fans, which is a major reason for overheating of laptops.

Hi all,

I have searched and searched for an answer to this problem, but can't seem to find a solution. Maybe someone here has a new idea...

Basically my computer suddenly stopped running on battery power. It had been working just fine until about two weeks ago. Here are the bullet points:

The computer won't turn on with battery installed unless the A/C adapter is also plugged into it. And, once on, the computer will shut down immediately if the A/C plug is pulled out.
The battery is relatively new (less than six months old.)
When pressed, the button on the battery itself indicates the battery is healthy (all lights illuminate, none flashing).
The meter on the computer indicates the new battery is working properly. When left out for a couple days and then put back in, the dell meter shows that it has lost 1% power and goes about charging it then successfully reports 100% charge after a while.
I've tried two old batteries (known bad, just haven't gotten around to taking them to be recycled) while using A/C adapter to see what the battery meter on the computer says... The meter displays an empty battery with a red x at the bottom when either of those is put in.

What I can't understand is why is it only working one direction? The battery will accept a charge from the computer then won't run off that charge later?

Other suggestions I've already tried, but haven't helped:
Verify computer has latest bios update.
Check for bent contacts.... Read more

I have a Toshiba Satellite laptop running Win XP. It's about 5 years old. The last couple of days, when I have it plugged in, the battery indicator icon acknowledges it's on AC Power, but the battery is still draining and the laptop turns off. I have not changed the power settings at all, but I checked them and all seems fine.

The battery is the original (came with laptop) and the AC adaptor is fairly new (purchased this year). This laptop did have problems with the AC port coming loose, which I fixed. Twice. First by soldering it back onto the motherboard, then by changing it alltogether.

As it stands, when my laptop is plugged in and turned on, the battery drains until it turns off (about an hour). The battery will charge when the laptop is off. The battery charge indicator (led) light turns OFF when I power up the laptop. It turns on again, when I power down. The battery will only charge when the laptop is off.

Is this a battery issue? An AC jack issue? An AC adapter issue? Does anyone have any experience with this? Sorry for length, but I am trying to foresee any questions anyone might have.
 

A:Toshiba Laptop & Battery Power

I would say it is most likely a battery issue if it is original, there is circutry in all laptop batteries that control charging and discharging and for safety. My guess would be start you search here, the battery is probably due for replacing anyways. If the adapter can charge it off then the adapter should be OK.

I've had this a while but never got around to getting ideas on the prob. 4 yr old Toshiba Satellite, Vista, updated OS/drivers... Most of the time it only boots with the power plug removed. After I get the windows loading scroll, I can plug it in and it boots fine. If plugged in while booting, it only gets to maybe the boot loader sequence and then powers off. If I run the boot repair, it may boot with power for a few times but always reverts to booting only without the power plug attached. Tried changing some system power settings with no change. I guess I haven't looked at the CMOS for anything odd. Battery seems to be charging/discharging OK. Boot load script seems normal. Any ideas?

(i'm used to hibernating my laptop, but i shut it down once every week) after that i could not make it start. it won't turn on, and the battery power LED on the side of it keeps blinking white for the whole morning!I tried battery, AC power, and both plugged in, but the power button exactly does nothing.i've found a table here with buttons flashing and sequences but neither matched my situation.I have to add that it has recently been warming up a little and had a few lags, which i guessed it's because of the new windows.please help me... i really don't want to hard reset my laptop because i have much data on it.thank you so much...

It goes like this: my laptop is normally plugged in, high performance power settings, battery taken out. Every once in a while I put the battery in and use it with normal charge/discharge cycles, power saving settings. Now it somehow happened that when I put the battery in and windows booted up I had no sound whatsoever. Chrome or AIMP2 are not recognized in the volume mixer, and skype notified me that it was unable to access the sound card. When I put it to sleep and then woke it up again the sound came back. I then followed the same steps: shut down windows, booted up, no sound, put it to sleep, woke it up, sound available, a few times and always with the same "results".

Does anyone have any idea what's going on ? This never used to happen before.

A:I have no sound when my laptop is on battery power

Reinstall the sound driver and see if that makes any difference. Sleep and what does or does not work after waking can be driver issues.

How is it booting? From a "cold" boot or booting up from Hibernate. If its booting from Hibernate that can be the cause of the problem (shouldn't be but can be).

Hello. My Lenovo Y450 laptop won't go to sleep/standby when its operating on battery power. It will go to tsleep if its plugged in to the AC adapter.

I have a Compaq Presario R3000 that I've owned for about 1.5 yrs. Several months ago, I noticed that it keeps switching to battery power even when plugged in. It used to happen when there was movement but now it can happen at just about any time. I assume it's a problem in the AC jack but what I want to know is....how much trouble is this to "fix"? Is it a fairly common problem with laptops?
Thanks
 

A:Laptop keeps switching to battery power

It's a very common issue with laptops, and I'd get it corrected BEFORE you end up with this! This is the second of two laptops I've seen in the last year that people ignored the advice to deal with the loose power connection.

As to how difficult it is to fix, that's going to depend on the specific make/model of laptop, and how much disassembly is required to repair/replace the jack.

P.S. Yes, the MB was destroyed and needed to be replaced in both laptops.

My friend's laptop won't turn on. It doesn't start to boot or anything. My first thought is it's either the battery or the A/C adapter but I'm not sure how to check those without having swappable pieces (which I don't have.)
I took the battery out and tried to power on with just the A/C adapter plugged in and same as with the battery in, only thing that happens is the little light with the lightening symbol flashes 3 times. Also the little light where you plug the charger in lights up while the charger is in. Would the laptop power up with just the A/C adapter plugged in and no battery?

I have a strange issue. I have a Lenovo T60 laptop and I am experiencing problems with the power management/power guage.

It will often show the battery not installed (power gauge is a greyish-white color with dashed lines) or it shows a red X. It does not matter if I am on AC power or on Battery power, it will show the full range of power, battery level, not installed, or an error.

I have searched Lenovo's site and I seem to remember seeing an FAQ about this, but now that I need it, I cannot find it.

What can I check or do to stop this? While it is annoying, I am not sure if I am having a battery problem or not. I did check my battery on Lenovo's site to see if it was recalled and it is not.

I do appreciate any help that any one can give me.

Thanks!

System: Windows 7 Home Premium SP1
Laptop: ASUS K52F with SSD; Laptop is almost 6 years old

When the laptop is on battery power, the laptop shuts down when the battery gets down to about 50-60%. This is a new behavior; the laptop did not behave like this in the past. The critical battery setting is at 10% so it should not shut down at 50-60%. I opened the laptop and checked for dust - it is clean since I periodically clean it. I scanned the laptop (in safe mode) with Malwarebytes, SuperAntiSpyware, ADWCleaner, Gmer, TDSSKiller, Avira - nothing found. Could this just be a bad battery? Or could the laptop be shutting down on high heat?

Any thoughts as to why this is happening and what I can do to solve this problem? Thank you.

i was working on a Dell Latitude 110L laptop for someone and I had to short two pins on the motherboard to erase the service tag and bios security password. the motherboard was placed upward and I was holding onto the battery attempting to do the short. while doing this i had the battery in. it was powering on fine then all of the sudden the battery fell out. after this the computer wouldn't power on without the AC power cord. the laptop wont boot up without the AC adapter in.

the power jack isn't broken (i used a multimeter to check).

I was thinking maybe I could solder a pin to the main source on the motherboard but I cant find it. Any tips??
also I might just order a new motherboard... however, I don't know if it's the battery. i'm afraid to check to see if the batteries good because I can't find information on the PINs to touch with the multimeter.

Hi all

I'm using a thinkpad T60. I think my battery is out, I've been checking it through the ThinkVantage and it said battery ok but should discharge and recharge. I did that and it was ok for a few weeks but power gauge always says 80%-90% and less than a hour, it goes into hibernation.

Now, without AC, my thinkpad can't be switched on. I leave the ac on while the battery is still attached to use it. The battery icon is orange and blinking. When I've shut down, I remove the ac plug. I've never removed the battery before since I've used this thinkpad 4 years ago.

Is this harmful to my thinkpad, all my data and stuff?
I'm reluctant to remove the battery in case dust gathers around the exposed portion. I'm also reluctant to buy a new battery as I'm thinking of getting a new netbook, those 10" type of laptop.
What's the best way to manage and keep using this thinkpad without a new battery, or is it a big NO NO???

Please help, I'm not very IT savvy. Thanks in advance!

About 4 months ago I performed a number of upgrades to my 4 year old Lenovo SL400 laptop.

I upgraded to a Seagate Momentus hybrid drive, upgraded my CPU, installed new RAM, purchased a new 9-cell battery and performed a clean intstall of Windows 7 Home Premium 64-bit (the computer came with Vista - Windows 7 was a retail upgrade).

I had several BSOD crashes which only happened when running on battery power. I was sure the battery was the culprit and RMA'd to the vendor for a replacement. I still have the issue with the replacement.

I notice a screen flicker a second or two before the crash. About half the time the computer recovers without crashing.

I've attached the dump files and system health report.

Any help would be greatly appreciated.

Thanks.

If you can answer this, you will have earned my undying admiration. Well, in truth you already have but still.... this is strange.
My brother has a Dell Latitude C600 which recently started giving him the blue screen "memory dump" crash. He had the hard drive replaced because that is what the tech told him it was. Still does it but he just noticed something.

He ran it for over three hours this morning on battery only and it was fine. then he plugged in the power cord and within 15 minutes, it crashed.

He charged the battery and tried the same thing with the same results only quicker to crash once he plugs in the power cord. It seem obvious that something is amiss here but I haven't a clue. I thought the power cord charges the battery which then powers the computer.

Anyway, this is totally unfamilar to me. I have heard of power cords failing to provide a charge but this is a new one. Any thoughts?

Thanks as always to you

I am writing this from my desktop. I just got a new HP Laptop (Pavilion) which came with a 45W power adapter. The power cord section (which plugs into the adapter) is shorter than the one on my older HP Laptop (G60-63OUS Notebook). I would like to have a longer power cord section or, in the alternative, could I/should I use an extension cord to reach the wall outlet I want to use. The older laptop has a 65w power adapter. I have 2 questions:

#1 - Can the power cord section from the 65w adapter be used in place of the one that came with the new laptop? I would, in effect, be mixing the two because the 65w adapter plug is too big for the hole on the laptop.

#2 - Can I get a higher power adapter for the new laptop or should I leave it alone?
Another question I have is regarding the use of cordless earphones to watch TV while working on the laptop. When the laptop is plugged in (to recharge the battery), I get static noise in my left ear. When on battery only, there is no noise. Is there a solution to this?
 

A:Laptop AC Power Supply Cord and Adapter

#1 Yes, if the older adapter's power cord fits into the new adapter you can use it.

#2 There's no need to get a more powerful adapter, the new laptop must not need as much power as the old one.

I currently have a XPS 12-9Q33 laptop that is not charging. The light at the end of the power adapter is no longer lighting up so it appears to be faulty. I've called Dell to purchase a new adapter but was told that they no longer sell replacements for them and was recommended to buy an adapter from a 3rd party source.
I purchased a replacement with the same voltage and amperage that is supposed to work on a XPS 12. The laptop now powers on but will not charge. The BIOS states that the adapter is unknown and will not allow it to charge.
What can I do now? I find it really frustrating that I cannot get a direct replacement from Dell themselves so I'm stuck with a laptop that is not portable at all since the battery is at 0%

The situation: Dell Inspiron 600M. Laptop won't turn on, when I press the power button, no response (at all). I think it's either the power supply or the adapter. The only reason I think it is the adapter is because the green LED doesn't come on, but the user said it hadn't been coming on for some time before the laptop stopped working altogether. The user has already gotten a new computer and really only cares about the data. I'm trying to decide the best direction to go: Adapter or SATA/ATA to USB converter? I'm pretty set on the converter, but want to make sure I won't have to reformat the HD for it to work with the adapter. I think the laptop has a PATA HD connection. Will it work on most of the converters?
Another side note: I have had no success yet finding another adapter that worked. I did try an adapter for an Inspiron e1705 (90W) and when I plugged it in it reset the adapter. I thought the adapter for the 600M was also 90, but I guess not.

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
 
Shockingly none worked that I found.
 
Only one thing worked for me to my surprise.
 
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
 
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
 
Thank GOD for bringing the idea to remembrance!

Hi guys,
I'm hoping some of you will be able to tell me what is going on with my laptop. Here's what happened- about a month ago (while I was in London for a weekend), I wiped Vista from my Toshiba Satellite M100 (it's about 2.5 years old) and replaced it with Windows7. Everything was great for a couple of days...then I came back to Amsterdam and plugged it in to charge, and realised it wasn't charging at all. I removed the battery completely and tried to turn my laptop on, and it seemed to be a problem with the power cord- it was totally dead. So, I ran to the nearest computer store, bought a new generic power cord, and my laptop was back on track! Or so I thought...

With the new power cord, the battery seemed to register that it was charging, but only briefly each time I plugged it in. As soon as the battery drained (which didn't take long as each attempt to charge it didn't go very far), the laptop would switch off. So, I removed the battery. I have been using my laptop sans battery for a month now, which isn't a huge problem. However, over the last week, my laptop has just completely blacked out a handful of times. The first time it happened, I thought it was because I'd somehow pulled the generic power cord out without noticing. When it happened again, I realised that my laptop really isn't happy, but I have no idea why.

Each time I have started my laptop after a blackout, it seems to be ok. One time, however, it went into... Read more

Over the last few weeks, I seem to be getting the BSOD frequently. Probably averaging at least once per day. Almost always, this occurs within 15 minutes of taking my laptop (Lenovo Thinkpad E530) off AC power and using battery power. Note that I'm usually watching a video and maybe have a few tabs open when this happens, so I'm not doing memory-intensive things and I don't think the laptop is being overheated or something. After the BSOD, I can usually reboot quickly and then get back and running smoothly, even if I just remain on battery power. Though it has happened where I got the BSOD consecutively.

Here is the error report I receive from Windows when I reboot:

My laptop will not stay on adapter power unless the adapter plug is pressed hard against the port. I bought a new adapter but the problem still remains so I guess it's the port's problem but I have no idea how to have it fixed. The laptop is no longer under warranty.

These ports are soldered to the motherboard. Replacing/repairing them consists of removing the motheboard from the laptop and soldering a new powerconnector on.

I have a Dell Vostro 1400 running Vista Home Basic and have had two periods in the laptop's existence where it would mysteriously freeze. You could see everything on the screen, and the power lights were on, but it would not respond except to a hard reboot by holding the power butting down for 5 seconds.

I am going through one of those periods now, and have discovered that the problem happens when I am either plugging or unplugging the AC power adapter, but don't know why. I have been all over the web for a solution, and while it does seem I am not alone with this problem, I have not read a sensible solution yet. My favorite bad answer is "don't unplug your laptop when it's on."

So, does anyone know what it could be? I wanted to look at system logs, and so went into the Event Viewer not even sure what to look for, but didn't see anything that looked like a likely culprit. Please help!

Thanks,
Neil
 

A:laptop freezes when plugging and unplugging AC power adapter

being a member of the Dell Community Forum, I looked there and found this

A lot things happen in Windows when inserting the AC power adapter.

To check if it's a classic CPU lock-up: repeatedly press capslock. If the capslock light doesn't change, there's no live in there.

Assuming the CPU is locked up: It's possible there's a log entry in the system log just before the AC power adapter is inserted. These entries give clues where to look, just before things went sour.

Next try to reproduce it in Safe Mode (press F8 when Windows start) If it's also in Safe Mode - try running an alternative OS (no need to install)

If the problem also shows up here - most likely it's a hardware issue.

Otherwise it's a windows issue - might be driver related.

the "alternate OS thing is a link on the forum web site. Click here to go to that site.

I've just had my adapter for two months and it's starting to show signs of 'aging'. It's a laptop adapter for Acer Aspire 5750G laptop. The problem is it doesn't work on certain extension wire socket that it USED to work on after 2 months. It only worked on direct sockets. The laptop's charging LED light would flicker orange-coloured on/off but the laptop itself would not charge. When I shutdown my laptop only then it shows a sign of chargingbut after a while, it would not charge at all from that particular extension socket. Other kinds of extension sockets also show the same result.

So, what's the real problem here-the extension sockets or the laptop adapter? By the way, I usually coil up the wires so that it fits into my bag. Is that one of the causes of this 'aging' phenomenon?

I have been looking for a decent adapter to use with my HP Pavillion ZV5340 that I just got for Christmas. We are heading to california next week and I'm looking for an adapter to use on the airplane (I'm not sure what type of plane it is, a jet is about it). I had read reviews for the N-Charge power supply, and that looks like it's a total fraud. So, I'm wondering what companies make decent, reliable power adapters for planes.....suggestions anyone?

Dear readers,

as the title states, my laptop randomly shut down twice so far when the battery was inside, but the AC power cable was in the computer. The battery icon bottom left indicated that it was 100% charged, running on AC power on High Performance and when I was in a game it randomly went off. Rebooted quicker than usual, skipping some of the startup processes it usually does when I manually turn it off.

The first time it did this the battery was very hot, even though it was running on AC. This time it is not, it is barely warm.

Another thing to mention is that both times, after being back in desktop, the battery would be "0% available (plugged in, charging)", but it would not charge, it stays at 0% until I remove it and put it back in.

I am having a problem while playing games as well, which we are discussing in another thread here:
http://forums.techguy.org/games/863611-significant-fps-drops.html

And here is my original thread:
http://forums.techguy.org/games/863947-large-fps-performance-drop-stuttering.html#post6949452

Hope someone has some insight on the matter.

Kindest regards,

A:Laptop randomly shuts down when running on AC power (when battery is inside)

Hi,
Some batteries can't take the electricity constantly flowing threw them i suggest you take the battery out when you plug it in the wall and put it in when your on the go. You battery does work still when you unplugg it from the wall right? And im guessing when your battery starts to fail it switches to "power saver" mode instead of "high performance" mode.
so take out the battery and plug it into the wall, store the battery until well until you need it. Hope this helps.
Also could be the result of a faulty battery..How long have you had your laptop?

I've read around a bit but nothing seems to be fixing my problem. My battery on my laptop died a few months back. I got the battery replaced last month and ever since I've been experiencing the BSOD for power driver failure once or twice a day. It rarely occurs while the laptop is in use. It's only when I open the laptop to restore it from sleep that I find it has crashed. Any help will be greatly appreciated. Thanks!

laptop battery is full, what happend if main power will fail for 10 minute during recovery setup. can it create a problem in resetting

A:laptop battery is full. what happend if main power will fail

Ideally you want mains power when in any setup, reset/recovery (to factory state) or restoring an image. Battery only "ought" to be OK as long the time required for the reset/recovery is well within the battery's available power time (if you see what I mean).Mac systems appear to insist on it baed on my own (limited) experience with them.If on mains, full battery and mains fails some time during the reset etc., as long as time left is within battery's time - ought to be OK.Just make sure before you do any form of reset etc., that any personal files (photos, music not the least) are safely duplicated off the system - to DVD at least; and verify the copies are OK before going any further.Others here may have different views; so wait and see what they add...

Hi if anyone can help i would be so greatful!!

I have a laptop which slows down as soon as i plug it into the mains. When running on batteries it is as fast as it should be and is perfect. I could comprehend the problem if it was the otherway around but this is too wierd.

I have rebooted the wholes system, it is clean as a whistle, over 30G of space, Virus checker / Firewall / ADaware remover / Registry cleaner / Defraged / Disk Cleanup - everything is in working order to keep this machine clean and healthy and it is.

The problem is most apparent when watching movies or clips, as the image goes out of sinc with the sound, freezes or goes super-slow, yet as soon as i remove the plug, and it's running on batteries it's fine again.

I know someone out there must have a solution.

thanks
 

A:Laptop runs slow when plugged in, but fine on battery power

Do you have access to another power cord to try. It kind of sounds like that there is a problem with the one that you have. I suppose that the problem could be internal to the laptop itself, but the swapping with a known good cord would tell you where the problem is. Of course, if you always use the same wall outlet, the problem could be there.

Hello, Tech Guy forums

So my laptop, which I got last December, freezes when running games (WoW, Champions Online, Aion are a few examples) on anything but power saver. Both Balanced and High Performance cause me to crash anywhere from 5-30 minutes after loading it up.

What happens is: I'll usually be doing some questing or whatnot and out of the blue for no known reason the entire computer just freezes. The sound cuts off, I'm unable to move the mouse. It stays this way unless I hold the power button to turn it off.

This problem is nonexistent when my laptop is set to Power Saver, which poses a problem as it causes low framerate when playing.

If anyone has any suggestions/questions/answers I'd love to hear em' ^^

Hello again,

I have seen these adapters that you can plug into a cigarette lighter outlet in a car, and use as the power source for a laptop. I tried before with one, but am not sure if it was the right wattage or what not.

My question is, where will I find on my laptop to see what type I will need? What number am I looking for to match up with the adapter? Also, are these adapters good?

Thanks.

A:What will happen if I remove the battery of a laptop and press the power button for 30 seconds??

It is a system reset - it resets the firmware to factory defaults.  If something is stored in CMOS that's preventing a boot, it will clear that -- it's a last ditch effort to confirm the fault lies elsewhere (usually with the mainboard).

Any idea what that is about? Perhaps my Firewall (Comodo)? No popup from it.

Not a biggie for me as I'm somewhat skeptical of anything automatic MS comes out with. But I am curious as to why my system is not supported by MS Fix.

Over the last 2 days I have been having a problem as indicated in the title of this post. The fault has rectified itself 3 times, but again today, it is back to "battery plugged in, not charging." As I am running the laptop (Windows Vista Home Premium; 32 bit) on the adapter without problems, I assume that the adapter itself may not be faulty.
I also have a Dell Inspiron 630M laptop running Windows 7.  Can I safely use that adapter with the Vista laptop, without causing damage to the Vista ?  If it is safe to do so, and the battery on the Vista starts charging, then it would indicate that the Vista adapter/charger has some kind of fault.
Hoping someone can give me some guidance. Thanks.

A:Dell Inspiron 1545 laptop. Battery plugged in not charging. Can I use adapter from a Dell Inspiron 630M laptop ?

If the adapter has the same plug and the same or higher power rating, you can swap them.
Check to see whether the 1545 recognizes the AC adapter or whether it shows unknown (F2 at powerup).  If it shows unknown with two different adapters, you have a bad power jack or a bad mainboard.

A:Dell Inspiron 5040N AC adapter Lost Power once plugged into Laptop

Hi RAYB871,
Please check if there is any damage on the machine. Check if all the ports on the machine are fine or misaligned. Sometimes if the pins in the USB ports are touching each other, they are known to cause many issues on the machine.
Three components cause this issue, in this order:
Adapter - you have already tested another adapter, so ruled out.
DC Port - the port that holds the adapter in, might be shorted - you would need this part - http://bit.ly/2bQ3HoP
Motherboard - I would primarily suspect this part, if the dc port does not fix the issue, then it is the motherboard that has failed and needs to be replaced.
If there is no warranty, then you could contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ
Personally, I would suggest, you invest your money on a new machine than to repair this old machine. However, it is your discretion.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.
Let us know if you have any other queries.

I just received my replacment AC adaptor. I put my battery back in and plugged the laptop in, but when i push the power button the battery indicator light flashes red four times. There are no lights on. Does this mean my battery is fried. Originally i thought the jack needed replaced, but the guy told me it was just my cord which Best Buy confirmed. So after getting the new cord i have this new problem. Usally there is a battery indicator light on when the battery is in and it is plugged in. I tryed taking out the battery, unplugging it and holding the power button down, but that didnt work. I also tryed it without the battery in. Is my battery just bad? Thanks for any help.

Thank you,
Dan

I'm wondering if there are any recommended external extended runtime battery options for the 7710 series laptop.
I see dell now has some external add-on battery options for longer runtime for the 5510 -- the Dell Power Companion 1800 mAh
accessories.us.dell.com/.../ProductDetail.aspx
but I assume it must not have sufficient output for the 17" 7700 series.
Is there an equivalent product for the 7700 series? I'd like to add 12 hours of runtime for a location that may have a few power outages a year and wouldn't mind buying a couple or few of these devices if there were one which was compatible.

This problem occurred with prior Win 7 Home O/S, so I upgraded to Windows 10. Heavens-to-Mergatroid!  This laptop runs just fine when only battery is powering it.  However, once I also plug in the power cord, the O/S does a hard crash within 1 to 3 minutes. How special! I can get about 2.5 to 3 hours when using the battery, but not if I also plug in the power cord.  That means that when the battery gets low I must perform a standard shutdown and then insert the power cord which recharges the battery if I don't turn  on computer.  If I then start the computer with both connected, it crashes.  I am not patient enough to live with a computer that has to be recharged every couple of hours.  HELP! I suspected a heating issue, so I took the back panels off and thoroghly cleaned the fan vents and other cracks and crevices using canned air, but this did not fix the problem.  Since in runs just fine on the battery, I deduce it is NOT a heating issue, neither dust or heat paste issues.  (I also used a cooling mat to no avail) Im 70 years old living in God's waiting room, but parts of my body are 18 to 30.  However, I do have "Essential Tremors" in both hands so I cannot do a full laptop disassembly even if I want to, which I don't.  I cannot afford to pay a computer repair shop $100 or more to try a fix this vexing power issue.  Other than hocking my car (it's too old also) to buy a new laptop, does an...

A:Battery - Vista is not able the retrieve the power options for the battery

Hi

To be honest I have no idea what you are talking about.
The Vista power options are a part of the Vista OS and you don?t need to install anything.

But on Toshiba notebook the Vista power option would be extended by some Toshiba power options.
Are you speaking about this Power Saver options?
If yes, then I would recommend reinstalling the VAP (value added package) because these power options are a part of VAP.
